Hi there, I have just updated to the latest version and it's great! Just one question...I'm finding it impossible to remove the "Powered by N-13 News". I deleted the small piece of code in the index.php but it's still showing up

The system has changed since then. I prefer users not remove the "Powered by" line of text. But the system is open source released under the GPL/GNU license so if you can figure out how to remove it, feel free to do so.
